Carrie Preston, who plays Arlene Fowler on HBO's True Blood, has been cast on CBS' The Good Wife for a multiple episode arc, according to Entertainment Weekly's Michael Ausiello. On the legal drama, the 42-year-old actress will play a character named Elsbeth Mann, one of the associates of Peter's (Chris Noth) legal team.

As of this moment, there is no word yet on when the True Blood actress will make her debut on The Good Wife. However, Preston's casting on yet another series is sure to ignite rumors about her fate on True Blood, which returns for its third season on June 13. And since production of the vampire series takes place in Los Angeles, it's not too far-fetched to speculate that she may soon drop out or possibly get killed off in the new season to make room for her upcoming gig, which films in New York.HBO Sets Premiere Date for True Blood Season 3

However, fans of Merlotte's quirky waitress shouldn't worry, at least for now. According to an insider, "Arlene isn't a major presence in the third book.

Preston is credited for her appearances on Law and Order: Criminal Intent, Private Practice and Lost, in which she portrayed the on-screen mother of her husband Michael Emerson. Besides True Blood, she's been busy working on several films these days, including What's Wrong with Virginia, A Bag of Hammers and Heated Rivalry.
